WHITFIELD :J'. HAINER, OF PROVIDENCE, RHCDE ISLAND, ASSIGNOR" 'IO VIRGINIA #MARITIME COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF MASS A- CHUSETTS.

To all whom it may concern:

Beit known that I, THITFIELD J. HAINER, a citizen ofthe United States, and resident of the city of lfrovidence,v in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Calking-Machines, of which the following is a specification. v

This invention relates to calking machines of the class more particularly adapted for use in the calking of seams in a vessels planking, and the object of this invention is to provide a simple and practical machine of this character which is adapted toautomatically operate one. or more calking tools for the. purpose of driving the calking material. into a seam as the machine is advanced along the work.

A further'object of the invention is to provide means in the machine for guiding it along the seams while driving the calking thereinto; also to provide means for controlling the fe ed of the calking as the machine is advanced.

Vith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure l-is a side elevation of the machine, showing the casing in section and illustrating the operating mechanism mounted therein.

Fig. 2is an outside view of the machine, showing the means for advancing the machine along the work; also showing the means for controlling therfeed oi the calking material;

' Fig. 8-is a detail showing an edge view of one of the guide wheels for engaging a scam in the planking to direct the machine along the work. y

Fig. 5is a perspective view showing a combined hammer and calking tool which is cut-away or slotted at its middle portion.

the frame or housingof the nia'chine, within which the calking mechanism is operatively mounted. This frame or housingismounted on four wheels 11, two Yon each of the two shafts 12- 12 thereby forming a carriage. on which I thefmachiiie is rolled along the seam ofthe work into which-031mm or. other calkinglmaterial is being'd'riven. H i

In order toguide this machineand insure its .tollowing [the seam in the planking, Iv

have mounted two.,guide-rol-ls13l3; one on each o'ftheshafts 12 within the; housing, which rolls are provided with "a chisel edge 14 adapted to enter the seam 15, .tokeep the Y machine proper alinelnent therewith while being passed along the work.

. Theoakum, cotton or 1" other c'alkingmaterial is driven or bored intotheseamsof the work rapidly bymeans of acombinedhammer and calkingitool whichl hereinaftercall the calking element.

In ,the present. construction I' have shown two .Ofthesecalking elements 16 and 17. The element 17 being made insubstantially the form of a hammer, the handle portion 18 being. pivoted on the shaft 19 and its extremity 20. being providectwith a friction roll 21 which is engaged by the operating cam The handle ofthis calking element is illustratedin Fig. 5 as; split practically throughout its length providing a longitudinally. disposed recess 23 therein. Across the back ofthis', handle I have formed a bridge 24 which is provided with an upwardly extending pin whiohprojectsinto the compression spring 26 which. spring drives the hammer downward after, havingbeen raised by means of the cam 22.

"The second calking element '16 isformed narrower than the element 17 but ofsubstantially the same general shape and is adapted to work in the space 23 ofthis element 17. This calking element 16 is, like the element 17, pivotally mounted on the pin 19, and is provided at its extremity 27 with a friction; rollQS which also engages andis operated by the cam 22. This second calking element 16 is arranged to be forced downward by the compression spring 31, the lower end of which engages the pin 32 thereon, after having been raised by the cam 22.

In each of these elements I have mounted chisel-shaped calking tools 29 and 30, respectively, which are held in position in each of the members by screws 55 and 56 whereby these calking chisels may be readily removed and replaced by others to fit the particular work at hand.

The cam 22 is mounted on the shaft 33 which is driven from the electric motor 34 through pulleys 35 and 36 and belt 37.

In order to advance the machine bodily over the work, I have arranged to drive the forward shaft wheel 12 through the worm gear 38, worm 39, shaft 40 and bevel gears 41 from the side of the electric motor opposite to that of the cam drive.

As the machine is moved along the surface of the work it is desired that the calking material be fed to the work at the speed desired, and that such speed should be readily controlled by the hand of the operator.

To accomplish this I have provided a pair of feed rolls 42 and 43, roll 42 being mounted on the shaft 44, which shaft is driven through the friction wheels 45 and 46 and 47 from the cam shaft 33 and in order to control the action of wheel 45 I have mounted an idler wheel 46 on the lever 48, which lever is pivoted at 49 and is provided with an operating handle 50 whereby a movement of the handle forward removes the face of the wheel 46 from contact with the face of wheel 47 thereby causing wheel 45 with its feed rolls 42 and 43 to cease rotating and so arrest the feed of the sliver of calking material 51. Suitable means being provided for holding said lever in adjusted position.

After this sliver of calking material passes the feed rolls 42 and 43 it is led around the face of the guideroll 52 which forces it down into the seams between the planks ready to be operated upon by the calking elements to drive it into the seams as the machine is moved along over the work.

I have provided a pair of handles 53 extending from opposite sides of the frame of the machine, which may be grasped by the hands of the operator when the machine is used on the side of a vessel, but when the machine is used along the deck of a vessel an operating handle 54 may be secured to these handles 53 so that the attendant may walk along the deck behind the machine to control its advancing movement.

The operation of my improved calking machine is as follows As the machine is moved along the vessels planking it is controlled by the hand of the operator either by the handles 53 or the handle 54. The electric motor is caused to rotate the cam 22 rapidly which in turn imparts a reciprocating action to the calking elements 16 and 17 causing them to strike the calking material and drive it into the seam with great rapidity, the calking material being fed from a reel or other source of supply (not shown) to the machine by means of the feed rolls 42 and 43. which rolls are controlled in their action by the movement of the feed-control handle 50.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that I re serve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A calking machine comprising a carriage, a combined hammer and calking tool operatively mounted thereon, means for feed ing the calking material to the work, means for controlling the action of said feeding means, means for reciprocating said hammer to drive the calking material into thework seams, and means for guiding said carriage along the seams of the work.

2. A calkingmachine comprising a carriage, a combined hammer and calking tool operatively mounted thereon, means for reciprocating said hammer to drive the call:- ing material into the seams, means for automatically advancing the carriage along the work, means for feeding the calking material to the work, and manually operable means for controlling the rate of feed of the calking material independent of the speed of travel of the machine.

3. A calking machine comprising a carriage, a plurality of hammer and calking tools operatively mounted one in advance of the other, means for feeding the calking material to the work, means for controlling the action of said feeding means independent of the speed of travel of the machine, a cam for reciprocating said hammers to drive the calking material into the work seams, and means for guiding said carriage along the seams of the work.

In testimony whereof I affix mysignature in presence of one witness.
